| titleOfInvention | A method for solidifying oil-based drilling fluid filter cake to improve cementing interface bonding strength |
| abstract | The invention relates to a method for solidifying an oil-based drilling fluid filter cake to improve the bonding strength of a cementing interface, comprising: (1) slowly adding base oil, slag, main emulsifier, auxiliary emulsifier, wetting (2) The agitator in the mud tank continues to stir until all the raw materials are evenly distributed in the oil-based drilling fluid; (3) Test the various engineering properties of the treated oil-based drilling fluid; The oil-based drilling fluid is pumped into the well, and through the drilling fluid circulation system, it participates in the drilling of oil and gas wells, and participates in the formation of well wall filter cake; , the slag in the filter cake is activated by OH- and continuously generates C-S-H gelation, which makes the oil-based filter cake solidify itself, and improves the interface bonding strength between the cement stone and the oil-based drilling fluid filter cake, thereby improving cementing. quality. The invention is safe, environmentally friendly, simple and convenient to operate, and can provide cementing quality assurance for subsequent construction of oil and gas wells. |
